IPC: F16D55/22
Filed: 1985-04-25
Abstract: PURPOSE:To optimize slide pressure distribution and prevent the roughening, breakage, and abnormal abrasion of a brake shoe by constituting the brake shoe with its center position displaced from the support center position of a piston toward the rear side in the rotating direction of a brake ring. CONSTITUTION:A brake shoe 1 is formed so that the center Cp of the piston 4 of a cylinder 3 operated via the air pressure is displaced by (e) from the center Cb of the effective length lo in the sliding direction of the brake shoe 1 toward the rear side in the rotating direction of a brake ring 6. Thereby, slide pressure distribution is high at the front side in relation to the rotating direction and is gradually decreased at the rear side, thus the slide pressure at the rear side is suppressed. Accordingly, smooth braking without roughening, breakage, and abnormal abrasion of the brake shoe 1 can be performed even at a high speed.

IPC: H02G15/22
Filed: 1995-03-20
Abstract: PURPOSE: To absorb thermal shrinkage at the time of cooling by employing a mechanism for sliding the cable terminal in the longitudinal direction depending on the measurement of variation in the physical amount incident to thermal shrinkage of the cable. CONSTITUTION: A stress sensor 13 is disposed at the joint of a thermally insulated inner pipe and a terminal and a motor 14 for driving a wheel 3 is controlled depending on the measurement of the sensor 13. In other words, when a cable 2 is thermally shrunk due to cooling, the thermal shrinkage is detected and measured by means of the stress sensor 13. Based on the measurements, a controller 15 operates a movement such that the stress being applied to the cable 2 or the terminal 1 comes within an allowable range. The motor 14 is then driven based on the operated value to move the terminal 1 in the shrinking direction thus absorbing thermal shrinkage. With such arrangement, the terminal 1 can be protected against breakdown.
